HORSESHOE-MACHINE.

Specification of Letters Patent No. 24,596, dated June 28, 1859.

To all whom i may concern:

Be it known that I, HENRY L. VA'r'rs, of Chester, in the county ofHampden and State of B'lassachusetts, have invented a new and usefulImprovement in Machinery for Making Horseshoes; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming part of thisspecification, in which- Figure l, is a plan view of my invention. Fig.2 is a vertical section in the plane indicated by the line y, y, in Fig.l. Fig. 3 is a vertical section in the plane indicated by the line a,af, of Fig. 2.

Similar letters of reference indicate corresponding parts in the severalfigures.

To enable others skilled in the art to make and use my invention i willnow pro* ceed to describe its construction and operation.

A, is a bedplate or horizontal frame which carries the workingl parts ofthe machinery.

B is a carriage to which the die C, for forming the interior of the shoeis attached, said carriage resting and traveling on a. planed surfaceprovided for it on the bedplate A, and being confined Jthereto by tongsa, a, on its sides fitting to grooved ways Z), 79, provided in thebedplate.

D, is an endless chain for driving the carriage B, said chain runningaround two wheels E, and F, secured to shafts G, H, at opposite ends ofthe ways on which the carriage travels, the shaft G, being the drivingshaft.

The die C consists of a plate of the intended form of the interior ofthe shoe to be made, having a flanch c, c, of corresponding form and ofa Width nearly equal to the width of the iron of which the shoe is to becomposed. The depth of the die below this flanch is just equal to theintended thickness of the shoe. The fiat bottom of the die fits to theflat surface of the carriage B, and the die has a vertical slot d, cl,through its center to receive a stationary upright e, which projectsupward from the carriage and which carries the fulcrum g, of aneccentric lever L, by which the die can be secured closely to thecarriage. Beneath the die there are applied two springs f, f, to raiseit from the carriage when released from the pressure of 2: the eccentriclever H.

The carriage B, contains two slots 7L, 7L, at eqaul distances from thedie C, and on opposite sides thereof; a short portion of each of saidslots commencing at their front extremities and terminating opposite thefront of the die, being straight and parallel with the direction inwhich the carriage moves, and the remainder corresponding in form withthe sides of the die. These slots, which are to effect the movements ofthe side followers I, I, and forming rollers J, J, receives portions ofthe axles z', z', of the forming rollers, which axles are fitted tobearings in the side followers. The side followers are fitted to slideat right angles to the movement of the carriage B, in suitable boxes K,K, cast with or bolted to the bedplate. I

The iron of which the shoes are to be made by the above-describedmachinery is cut to the proper length from bars of suit able size, andbefore being introduced to the machine is heated and swaged to therequired form throughout its whole length.

I have represented, attached to the side of the machine, a suitable setof swages M, M, N, N, for this purpose and for punching the holes,secured in the block P, which is fitted with an adjustable gage Q, andintended to have a trip-hammer operating above it. The pieces of iron,after having been swaged to the suitable form, if not still suflicientlyhot, are re-heated and placed singly across the front of the die C, andbehind the forming rollers J J, while the carriage is stationary and thedie is held up by the springs f, f. The lever L, is then moved to bringdown the die, and after that is done the shaft G, is operated to movethe carriage forward, viz. in the direction indicated by the arrow uponit in Fig. l, which movement driving forward the piece of iron(represented in red color in Fig. 1,) between the rollers J, J, bends itclosely around the die C,to the desired form. The carriage is then runback, and while it is running back the lever L is raised to liberate thedie C, which is then raised by the springs 7", f, to liberate the shoe,and permit its removal by a pair of tongs. As soon as the carriage hasmoved back far enough, another piece of iron is put in, and the movementof the carriage reversed to repeat the operation. Vhenever it isnecessary `to change the form given to the shoe it is only necessary toremove the slot-ted carriage B, which Slotted Carriage B,v the die C,the followers is merely a flat plate and substitute another I, andthe'rollers J, as and for the purpose having slots so made as to impartthe form herein ebown and described.

desired to the shoe-blank. H. L. WATTS. 5 Having described my inventionI claim Vitnesses:

and desire to secure by Letters Patent, Y FORBES KYLE,

The arrangement and combination of the ABNER SAMPSON.
